To calculate the frequency in megahertz (MHz) corresponding to a given wavelength, you need to convert the wavelength from meters (m) to the desired unit, in this case, megahertz.
The formula to convert wavelength to frequency is:
f = v / λ
Where:
- f is the frequency in hertz (Hz),
- v is the speed of sound in the medium (m/s), and
- λ is the wavelength in meters (m).
To convert the frequency from hertz to megahertz, divide the frequency by 1,000,000 (since 1 MHz equals 1,000,000 Hz).
So, to calculate the frequency in megahertz corresponding to a given wavelength, you can use the following formula:
f(MHz) = (v / λ) / 1,000,000
Please note that the speed of sound varies depending on the medium through which it travels. In air at room temperature, the speed of sound is approximately 343 meters per second (m/s). However, in other mediums like water or solids, the speed of sound can be different.
By substituting the appropriate values for the speed of sound and wavelength, you can determine the corresponding frequency in megahertz.
